AUTOMATIC DUMPING DEVICE FOR ORE-BUCK'ETS.

SPECIFICATIQN forming part of Letters Patent No. 735,571, dated August4, 1903.

Application filed April 7, 1903. Serial No. 151,479; (No model.)

T all whom it may concern:-

Be it known that 1, ROBERT NYE, a citizen of the United States, residingat Moline, in the county of Rock Island and State of Illinois, haveinvented new and useful Improvements in Automatic Dumping Devices forOre-Buckets, of which the following is a specification. V

My invention relates to automatic dumping devices for ore-buckets, andhas for its object to construct a simple counterpoised carrier toreceive an ore-bucket and dump it without danger of'spilling any of theload into the shaft.

The simple and novel construction employed by me in carrying out myinvention is fully described and claimed in this specification andillustrated in the accompanying drawings, forming a part thereof, inwhich- Figure l is a side elevation of my device with the doors up,bucket down in the shaft, and the carrier in its normal raised position.Fig. 2 is a rear elevation with bucket raised and the doors closed. Fig.3 is a side elevation of the bucket resting on the heel-block and withother positions shown in dotted lines.

The numeral 1 designates a housing built over the mouth'of a shaft.One-half of the top of the housing 1 is cut away on one side at 2 on anangle of about forty-five degrees, and the casing is normally closed bya horizontally-extending -door 3 and an inclined door 4, both hinged tothe casing 1. A triplever 5 is fulcrumed at one end on a pin 6,

seated in the casing 1, and is connected by link-bars 7 and 8 to thedoors 3 and 4, respectively. Trip-lines 9 and 10'are connected to thefree end of the lever 5. They pass over sheaves 11 and are connected. toopposite ends of an engineers lever 12, fulcrumed intermediate its endson a pin 13, seatedin a standard 14. Gounterpoise-weights 15 areconnected to the doors 3 and 4 by suspensioncords passing overguide-sheaves 16. These block 24, mounted on the door 3 to one side ofthe center of gravity of the bucket 17 as it is suspended by the cable18. Mounted on the door 4 and extending parallel to the heelblock 24 isa toe-block 25, rounded out at .25 on the contour of the bucket. Toembrace the bucket and support it during the act of dumping, ayoke-shaped carrier or carriage 26 is pivoted by its cross-bar 27 to thetoe-block 25, with its parallel arms 28 extending at about an angle offorty-five degrees to the vertical and with their extremities bent at aright angle to form toes 29, designed to engage the rim of the bucket17. Counterpoiseweights 30 are connected to the carrier 26 by means ofsuspension-cords 31, passing over a sheave 32- A head-block 33 ismounted on the casing 1 just below the door 4 in position to limit thedownward swing of the carrier 26 and bucket 17 and is rounded out at 33to accommodate the bucket.

In sketching the operation of my device, I will suppose its initialposition to be that illustrated in Fig. 1 of the drawings. As the bucket17 is raised through the action of the hoisting-engine and cable 18 itwill pass up through the open doors 3 and 4 and the bail 17 a willengage the guide-bar 23 and be brought into position with its curvedarms resting against the bar. This will bring the bucket 17 in properposition with respect. to the heel-block 24. The doors 3 and 4 are thenclosed by means of the engineers lever- 12 and connecting mechanism,after which the cable 18 is slacked off by the engineer andthe bucket 17lowered onto the block 24, when further slacking will permit it to tiltto the left into the embrace of the carrier 26. As soon as the weight ofthe bucket rests in the carrier 26 it willovercome the weights 30 andswing the carrier 26 to the left and the toes 29 will hold the bucketfrom slipping ofi after it has passed the horizontal. As soon as theload is dumped the bucket 17is pulled up by the cable 18, when theweights 30 willrestore the carrier 26 to its initial position. The

doors 3 and -l are then raised by the use of lever 12, after which thebucket is lowered and the operation repeated.

I do not wish to be limited as to details of construction, as these maybe modified in many particulars Without departing from the spirit of myinvention.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. In a device for dumping buckets, the combination of an incline, ayoke-shaped inclined carrier pivoted to the upper end of said inclineand bearing feet for engaging the rim of the bucket, acounterpoise-Weight connected to said carrier to retard the tiltingmovement of the bucket, and a heel-block located to be engaged by oneside of the bucket to tilt it into the embrace of the carrier.

2. I11 a device for dumping buckets, the combination of an inclinedbase, a pivoted inclined carrier bearing upwardly-extendin g armsbearing toes on their upper ends to engage the rim of the bucket, acounterpoise connected to said carrier, and means for tilting the bucketinto the embrace of said carrier, substantially as described.

3. In a device for dumping buckets, the combination of an incline, acarrier pivoted to said incline to embrace a bucket and permit it totilt over and dump, a counterpoise connected to said carrier to retardthe movement of the bucket, and means for tilting said bucket into theembrace of said carrier, substantially as described.

4. In a bucket-dumping device, the combination of a downwardly-inclinedplane, a carrier pivoted to the upper end of said plane and inclined tothe Vertical, a counterpoise connected to said carrier, aheel-blocklocated adjacent to said incline to engage the bucket and tilt it intothe embrace of said carrier, and aguide-bar located to engage the bailof the bucket to bring it into position above said heel-block,substantially as described.

5. In a bucket-dumping device, a casing mounted over the mouth of ashaft, two swinging doors closing said casing, a triplever fulcrumed atone end and connected by link-bars to said doors, an engineers leverfulcrumed intermediate its ends and tripcords connecting the free end ofsaid triplever to opposite ends of said engineers lever, substantiallyas described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesscs.

ROBERT NYE.
